Cycle Progress

[dave_paton]

Ok here we go,

last 2 days i had my first readings of nitrite, my first was at 0.25 so i did a water change about 25% (this was the friday night) then i went away on the satday morning just for a little surf trip. Got back just now (sunday night here is aus) and my nitrite wsa at 2!!!!! holy crap!!!!

so i did a large water change and now its back down to 0.50
il be doing another water change tommorow night also, to try and get it back to 0 or at least under 0.25.

Is everything ok or is my tank spiraling out of control

ammonia : less than 0.25
nitrite : 0.50 (curently)
ph : 6.8 constant
kh : 4
Gh : 7

tank : 143L jebo r362
few plants and drift wood
4 gold barbs and 2 three spot gourami
had fish in for 3 weeks all look and acting healthy

Thanks in advance for replies and advice!!!

Not the worst that I have seen the nitrite and ammonia, as you probibly know, are both toxic to fish Any detectable reading is bad long-term, and anything over 0.25 can be risky short-term, so I'd test in the morning and plan the waterchange size arround the results. Try to keep the levels of ammonia and nitrite below the 0.25 mark and you should be fine

If you haven't already, I surgest that you have a look at [topic="224306"]this thread[/topic] that explains fish-in cycling in more detail.

thanks rabbut
yeh i did another large water change tonight i came down from 1 to 0.25 or maybe a bit less but its a bit hard to tell, do you no how long this stage of the cycle takes?? i was wondering when the daily water changes would come in lol and here they are... nevermind, learning from my mistakes. ive read that thread a few times it quite helpfull and i am referering to it alot.
thanks again

really there's no way of measuring the time it'll take, there's so many variables that affect it that we've no way of predicting it.

can't say the results sound good, but they are as expected for this point in the cycle. Just keep up the daily water changes and you'll get there. Glad the fish seem to be doing well.

ok cool, yeh i no its not good. but ahwell i suposed since i am doing a fish in cycle it has to happen for the filter to produce bacteria that fights nitrite. ill keep you guys posted anyway of what is happening.
again thankx for the advice
love the forum
